Projections or lugs at each end extend out upon each side below the axle and have holes made through them to admit the threaded ends of the clips 10. The clips pass over the wooden upper portion 11 of the axle, one passing through the holes of the clip-yoke beneath the part A and the other passing through the holes in the yoke beneath the part 32. When these are securely screwed down,the joint is strengthened by the cli p-yoke 9, which crosses it, and this clip-yoke also prevents the unscrewing of the part 3 and the spindle carried by it.

The usual braces may be connected with the clip-yoke, extending from thence to the reach or other part in the usual manner.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. The combination with an axle, of stubs having cylindrical extensions with screwthreads at the inner portions, and a tubular spindle tting over each of the said extensions and having substantially square extensions at the inner end corresponding approximately in shape with the axle, said square extensions being internally threaded to engage the threads at the inner end of the tubular extension of the stub.

2. The combination with an axle, of a stub having a cylindrical extension provided, at the inner end, with screw-threads; a tubular sleeve extending the length of, and fitting over, the cylindrical extension, and having a square extension at the inner end fitting over the threaded portion of the cylindrical extension and internally threaded to engage the latter, means for clamping said Vextension of the sleeve and the stub to a main portion of,

the axle, and a nut upon the outer end of the cylindrical extension for retaining the wheel in place.

3. The combination in a wheel-axle of the stub having a cylindrical extension, a sleeve or spindle fitting saidextension forming a bearing upon which the wheel-hub box turns, said cylindrical extension having a threaded portion at its inner end and said sleeve having a square extension at its inner end internally threaded to engage the threads of the cylindrical extension, and means clamping the squared end of the sleeve extension to a main part of the axle, said cylindrical extension having threads upon its 'outer end, and a chambered nut iitting upon said threads adapted to contain washers whereby compensation for wear-is effected.

4. The combination in a vehicle-axle of a stub having a cylindrical screw-threaded extension, a tubular sleeve or spindle itting over said extension having the inner end screw-threaded to t corresponding threads of the stub whereby the two parts are united with the rectangular portions of the axle coincident, a clip-plate extending across beneathV
